Problems solved by technology

At present, it is generally used to carry out vibration polishing or shot peening treatment to carry out surface strengthening after abrasive belt grinding and polishing. The above process combination not only increases the production cycle of parts, but also increases the production cost. At the same time, the tensile stress will lead to an increase in surface roughness

Description

technical field [0001] The invention relates to the field of structural design of an abrasive belt grinder, in particular to a three-dimensional ultrasonic vibration-assisted abrasive belt grinding device. Background technique [0002] Ultrasonic vibration-assisted machining has been widely used in many machining fields such as turning, milling, grinding wheel grinding due to its excellent performance in reducing cutting force, extending tool life, improving surface quality, improving microstructure properties, and improving surface integrity. Applications. Belt grinding and polishing, as the final treatment process for complex curved components such as aero-engine blades, can eliminate the machining allowance and machining texture of the previous process, and directly determine the final surface state and surface performance of the parts. However, while the abrasive belt grinding and polishing process removes machining allowance and machining texture, it also removes the s...
